A low frequency AMD product against a high frequency and slightly overheating Intel product, but this time with a more balanced IPC between the two. This is Athlon 64 vs Pentium 4, round 2. Freaking finally.

Wait. What? You mean having an 8c/16t CPU with 5Ghz it's not even trying? You're joking right? :laugh::laugh:
I wan to see a simmilar AMD CPU going on stock air cooler on the same freq without any o.c.
Air cooled you say? I'm sure those pipes there were blowing air. Plus the 1600Watt PS that could run almost my entire house devices. What a bull crap on a barn floor dude. Start from 8 minute and go from there.

Regardless if these leaks are true or exaggerated. AMD is on the right track. not like Intel with their new 8C/8C without hyperthreading.. again if the leaks are true.

That 8c/8t is the best thing that could happen for gaming. Look how stellar 8600k performs against 8700k, now add +25% more cores and +33% more cache.

Hold on now.

- Intel K CPUs are not supplied with stock coolers at all, and we know why: its pointless
- Since Kaby Lake Intel is just providing its CPUs with factory OC's. There is a reason the TDP jumped up to 95W and they go way beyond that if you so much as look at the BIOS.
- Intel relies heavily on binning, another aspect AMD has them beat from a design/yield perspective.

10% IPC increase isn't the same thing as a generic 10% increase in single thread performance and the fact that the article sort of refers to them as being interchangeable metrics annoys me.

Zen's IPC is already on par with something like Coffee Lake , minus AVX.
Minus AVX ? All ZEN based CPU's support both, AVX and AVX2. Unless you meant something else with that...

Zen can do 2x 128 bit FMAs per clock cycle whereas Skylake and upwards can do 2x 256 bit.

But what has FMA to do with AVX? Isn't FMA a separate instruction set for a different thing?
FMA is a type of operation not an instruction set , well there is an instruction set named FMA but really it's the same thing.

What I mentioned is the hardware support for instructions like AVX. AVX is an instruction set that can allow for 256 bit wide hardware registers or 2x 128 bit ones. AMD chose the latter , therefore instructions such as AVX are carried out at half the throughput that Skylake can do. In practice it's never really half , the gap is much smaller but it's there.

For anyone interested, new leaked roadmap from Intel confirms no 10nm till 2020 at the earliest lol:

https://wccftech.com/intel-xeon-scalable-family-roadmap-revealed-points-out-cascade-lake-sp-in-q4-2018-cooper-lake-sp-in-q4-2019-ice-lake-sp-in-1h-2020/


I really can't decide how much I want Intel to be skullcrushed. I want them to really learn their lesson so they never let themselves stagnate like this again, but at the same time it looks like they might be in almost as bad a position as AMD was by 2021 - and I do not want AMD to simply become the new dominating force without competition. At this point it looks like AMD may have 7nm+ out before Intel launches any 10nm product...

Who knows, maybe Intel will become so desperate they actually launch Graphene 1nm chips in 2025 or something...

While the IPC uplift that the rumor claims would be great, due to how Zen architecture works, i'd rather they work on having the ability to use rated RAM speed for high speed RAM, such as the one from the example in the post above from @ToxicTaZ . This alone would greatly increase Zen chips performance across the board. Managing to add like 3% - 5% IPC would be the cherry on top.
Why? Faster memory only helps workloads which are bottlenecked by memory bandwidth. And if you really need more bandwidth, go with HEDT and get twice the bandwidth.

That 8c/8t is the best thing that could happen for gaming. Look how stellar 8600k performs against 8700k, now add +25% more cores and +33% more cache.
If you mean 8 vs 6 cores, that's 33% more cores.
Just FYI, even though L3 cache is shared, it's still tied to a core. This means L3 cache may only benefit other cores if two or more cores accesses the same data within a very short timespan, it's not like one core can "borrow" the L3 from another.

But yes, it will be a nice product.

Zen can do 2x 128 bit FMAs per clock cycle whereas Skylake and upwards can do 2x 256 bit.
And Skylake-X/-SP can do 2× 512-bit FMA.

But what has FMA to do with AVX? Isn't FMA a separate instruction set for a different thing?
FMA3 is an extension to AVX introduced by AMD(!). It performs operations like a × b + c in a single operation, which speeds up many types of calculations like matrix multiplication. But it saves more than you might immediately think, since the single operation saves a whole cycle through the pipeline.

Again, due to how Zen architecture works, the faster the memory, the faster infinity fabric operates, which translates into performance increase. This is why faster memory is recommended, when going for a Ryzen system. I'm not only referring to the normal timings: the sub-timings are also important in a Ryzen system.

Unfortunately, even though RAM with 3600+ speed is available and has been for quite some time, Ryzen has been unable to take advantage of this and you'll be hard pressed to find Ryzen systems working with RAM @ speeds 3600+. They exist (i've seen 4000 myself), but they are very uncommon because tinkering with the sub-timings is required in order to get it to work: something you usually don't need in an Intel system because you're normally able to have the rated XMP speeds simply by selecting them in the BIOS.

Yeah the price fixing on DDR couldn't have come at a worse time for AMD. Having said that, I still think it's ridiculous that PC Hardware journalism continues to ignore the fact that 3600MHz+ RAM makes Ryzen better than Intel at gaming (Even if Intel is @5GHz+).


This is an incredible point people are missing: If you care about Price/Perf (at any resolution), Ryzen 2 is the obviously better choice. If you care about just having the highest performance possible, then you should ALSO choose Ryzen with fast memory.

Except for the tiny fact that the cost/performance perspective is lost on the Ryzen option altogether then :) Just as much as it is on Intel with a nice OC, and probably even more so.

The tweaking required to get Ryzen to optimal performance is still too much for most people. So Intel's winning because it offers almost the same but in a much easier way, and often cheaper even on its most expensive mainstream CPUs. Fiddling with timings is advanced user niche territory. An OC on Intel is really not - as much, at least.

1. If you want price/perf - nothing is going to beat a Ryzen build the saves money where possible.

2. If you read what I said, anyone getting an 8700K doesn't care about Price/perf (if they did, they wouldn't even glance at Intel). So the "Extra cost ruins the value" BS is really not true for these people.

3. In terms of Enthusiast Price/Perf, you are still wrong. Ryzen is cheaper AND better performing. Here are 2 different ram kits:

https://www.newegg.com/Product/Product.aspx?Item=N82E16820313771&cm_re=DDR4-_-20-313-771-_-Product

https://www.newegg.com/Product/Product.aspx?Item=N82E16820313618&cm_re=DDR4-_-20-313-618-_-Product

It only costs $70 to go from 2400 to 3733 memory! That's less than the price difference required to buy the 8700K (+$50), the AIO Liquid Cooler (+$75), and the more expensive Intel motherboard (+$25). You are actually saving a lot of money (and energy usage) by going with the 2700X + Fast RAM instead of the 8700K + Peasant RAM. Also, it is going to beat the 8700K system at gaming and allow upgrades to 7nm Zen next year.

Dude: let's not kid ourselves.

Sure: 2700X catches up to Intel (and passes, on some instances) when overclocked with RAM using good timings in gaming but, as soon as you overclock the 8700K, it's game over, simply because the 8700K overclocks allot more, and even further if you end up de-lidding. I think it's more "common" to find 8700K running @ 5.2 GHz then it is to find a 2700X @ 4.4 GHz and that clock speed difference is simply too massive atm for AMD.

You'll need to spend some cash to achieve a good OC on 2700X, both on RAM and in cooling, which can be as low as you said but can also be quite significantly higher, depending on where you live. The same is true for the 8700K but you're forgetting that those that buy the 8700K also tend to pair it with good RAM which, although doesn't give a gain as big as it does in a Ryzen system, still gives it. This will ofc make the 8700K system even more expensive but also even better performer.

No, it doesn't. Actually look at the attachment (and other information found on the internet). That is a $170 R5 2600 @4.2GHz matching a $350 i7 lol. A 4.4GHz 2700X would easily win (and still cost less).

Heck in that benchmark they used ram slower than I found for cheap!

While having quite lower min FPS. Dunno about you but to me, the min FPS is the more important of the two.

If you "pull all the stops" to make the Ryzen faster, it will surpass the 8700K but, if you do the same to the 8700K, it pulls even further ahead and that's the problem here because, and unless you have bad luck with the 8700K (silicon lottery), it will overclock past the 2700X every single time.

This WILL change when AMD increases the IPC but that depends on how much it increases and even then, it could still lose to Intel, depending on how much it OCs (or doesn't).

Very funny

Unfortunately for your point you missed the point. Intel is still releasing 10nm Icelake S for mainstream next fall. You're article is only Server/Work Station are not getting 10nm in 2019.

So all Intel fans don't have to worry about 10nm next year for Dual channel launch.

I Reilly hope Zen 2 IPC is big improvement and get a little better closer to Intel IPC performance and trying harder and harder to get all around better performance!

It only makes, Intel do something otherwise they sit back and milk it.

Intel is 100 times bigger than AMD so if if there wasn't a law in place of buying out your compilation in place, Intel would throw pocket change at AMD.... Done

So Zen 2 vs Icelake next year going to be amazing.

Just to add some data, I used to run my 2700x @4.3 with 3600mhz memory. I have since scaled it back to 4.15 for 24/7 use cases with the same memory speeds(16 cas). All I did was set it n forget it no real extra tweaking.

If you manage to fine tune your sub-timings @ that speed, you'll probably be getting better performance @ 4.15 then you did @ 4.3: it depends on the tuning.

EDIT

Look @ the following, and pay attention to only the graphs with RAM @ 3200 MHz:



As you can see, there's quite a difference between them, with just messing on the timings. Only the blue one to the right has a different CL timing but all the others have CL14.

Very funny

Unfortunately for your point you missed the point. Intel is still releasing 10nm Icelake S for mainstream next fall. You're article is only Server/Work Station are not getting 10nm in 2019.

So all Intel fans don't have to worry about 10nm next year for Dual channel launch.

I Reilly hope Zen 2 IPC is big improvement and get a little better closer to Intel IPC performance and trying harder and harder to get all around better performance!

It only makes, Intel do something otherwise they sit back and milk it.

Intel is 100 times bigger than AMD so if if there wasn't a law in place of buying out your compilation in place, Intel would throw pocket change at AMD.... Done

So Zen 2 vs Icelake next year going to be amazing.
"Next fall". You mean after 16-core 5GHz Ryzen 3 is out? Who cares at that point?!

And come on, everyone with a brain knows it's like a 66%+ chance that it slips to 2020.

1. If you want price/perf - nothing is going to beat a Ryzen build the saves money where possible.

2. If you read what I said, anyone getting an 8700K doesn't care about Price/perf (if they did, they wouldn't even glance at Intel). So the "Extra cost ruins the value" BS is really not true for these people.

3. In terms of Enthusiast Price/Perf, you are still wrong. Ryzen is cheaper AND better performing. Here are 2 different ram kits:

https://www.newegg.com/Product/Product.aspx?Item=N82E16820313618&cm_re=DDR4-_-20-313-618-_-Product

It only costs $70 to go from 2400 to 3733 memory! That's less than the price difference required to buy the 8700K (+$50), the AIO Liquid Cooler (+$75), and the more expensive Intel motherboard (+$25). You are actually saving a lot of money (and energy usage) by going with the 2700X + Fast RAM instead of the 8700K + Peasant RAM. Also, it is going to beat the 8700K system at gaming and allow upgrades to 7nm Zen next year.
You realize there is also an 8600K that has 100% similar gaming performance and will cut the cost down slightly below the Ryzen with fast memory option? AND clocks higher on average than the 8700K at less heat = lower cost of cooling?

Quit acting like you've found the holy grail or something. The landscape hasn't changed - Intel is the top option for high refresh rate gaming - cost and performance wise with the 8600K and 8700K respectively. For everything else, Ryzen 2 is the go-to option. And that's still quite a feat.
